Year Light-Duty Vehicle Greenhouse Gas Emissi ons and Corporate Average Fuel Economy 
Standards (567 pages, in English)     
6. Description of content:  EPA and NHTSA, on behalf of the Department of Transportation, 
are issuing this joint proposal to further re duce greenhouse gas emissions and improve fuel 
economy for light-duty vehicles for mode l years 2017-2025. This proposal extends the 
National Program beyond the greenhouse gas and corporate average fuel economy standards 
set for model years 2012-2016. On 21 May 2010,  President Obama issued a Presidential 
Memorandum requesting that NHTSA and EP A develop through notice and comment 
rulemaking a coordinated National Program to reduce greenhouse gas emissions of light-duty 
vehicles for model years 2017-2025. This proposal,  consistent with the President's request, 
responds to the country's critical need to a ddress global climate chan ge and to reduce oil 
consumption. NHTSA is proposing Corporate Average Fuel Economy standards under the 
Energy Policy and Conservation Act, as amende d by the Energy Independence and Security 
Act, and EPA is proposing greenhouse gas em issions standards under the Clean Air Act. 
These standards apply to passenger cars, li ght-duty trucks, and medium-duty passenger 
vehicles, and represent a con tinued harmonized and consistent National Program. Under the 
National Program for model years 2017-2025, auto mobile manufacturers would be able to 
continue building a single light-duty national fl eet that satisfies a ll requirements under both 
programs while ensuring that consumers still have a full range of vehicle choices. EPA is also 
proposing a minor change to the regulations appl icable to MY 2012-2016, with respect to air 
conditioner performance and measurement of nitrous oxides. G/TBT/N/USA/665
